1:Session 'example': Error Installing APKs
1.重新编译
2.重新插拔数据线
3.更改Studio的设置,将下方的第一个复选框的勾去掉
file-Setting-Instant Run
2:Error:Execution failed for task ':example:preDebugBuild'.
> Android dependency 'com.android.support:support-v4' has different version for the compile (22.2.1) and runtime (26.0.2) classpath. You should manually set the same version via DependencyResolution
解决办法:
项目中Project build.gradle(不是model),添加
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "26.0.2"
}
}
}
}
3:activity界面一片空白的现象。
老版本的adnroid sdk中对activity进行初始化,一般都是在oncreate(Bundle saveInstanceState)中进行,
5.0之后,多出来一个oncreate(Bundle saveInstanceState,PersisitanbleBundle persistentState);函数。
如果我们对布局的初始化放在了第二个中,则会显示一片空白。
解决方法:将对布局的初始化等操作放在oncreate(Bundle saveInstanceState)函数中进行
